To all whom it may concern-.-

Be it known that I, HERBERT SMITH, of the city and county of \Vorcester,and State of Massachusetts, have invented certain new and usefulImprovements in \Yire-Drawing Machines; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, forming a part of thisspecification, and in which Figure 1 represents a plan view of awiredrawing machine embodying my improvements. Fig. 9 is an end viewthereof with the driving-pulleys, as well as wire reel and block, leftoff, looking in the direction of arrow a in Fig. 1. Fig. 3 is a sideview of one end of the back of the machine looking in the direction ofarrow 1) in Fig. 1. Fig. 4isa side view of one end of the front of themachine looking in the direction of arrow 0 in Fig. 1; and Figs. 5, 6,7, and S are a front view, plan,

central longitudinal section, and central transverse section,respectively, of the die holder or support.

My invent-ion relates to improvements in wire-drawing machines having aseries of dies, through which the wire is drawn and reduced severalsizes by a continuous operation; and it consists in the construction,arrangement, and combination of parts hereinafter specified, whereby theabove result is effected, the essential feature being to produce amachine which shall run smoothly with theleast possible vibratorymotions, as and for the purpose hereinafter more fully set forth.

Following is a detailed description of my said invention with referenceto the accompanying drawings, enabling others to fully understand thenature and purpose thereof.

The various parts marked A represent the main frame-work of the machine,made in practice of the proper shape to support the various operatingparts.

B is the main driving-shaf t, fitted to turn in suitable bearings, 13B,in frame A, and having at one end the fast and loose pulleys O C,which may in practice be connected, as usual, with any suitable drivingmechanism. Upon said main shaft B are mounted a series offriction-disks, Dfive in this instance whose hubs D engage with theupper ends of clutch-levers E, arranged in this instance under each hub.The lower ends of said clutchlevers are fitted over horizontallongitudinal threaded shafts F, one for each clutch-lever, and fitted toturn in suitable stationarybearin gs, F F. Said threaded shafts are heldagainst longitudinal movement in their bearings, and are turned by meansof a handwheel, G, on the end of each shaft.

The disks D are fitted to slide longitudinally on the shaft B, but areheld against rotary motion thereon by means of the featherkey (I, whichis preferably extended the whole length of the shaft between itsbearings. Said disks D- engage with a series of disks, H, arranged atright angles to and upon a line horizontally therewith. The latterdisks, II, are mounted on the outer ends of a series of horizontalshafts, I, arranged at right angles to.

the shaft B and fitted to turn in suitable sta tionary bearings, I I, inframe A. Upon said shafts I, between the side frames, A A of frame A,are mounted the friction-cones J, and above said friction-cones aremounted, on shafts K, similar friction-cones, L, the cones beingarranged in a seriesof pairs in line horizontally lengthwise of themachine, with the cones of each pair beveled in opposite directions, asis illustrated in Figs. 1 and 2, and at sufficient distance apart toadmit a frictionbelt, M, between them, the purpose of thus interposingthe belts M between the cones being to admit of imparting a varyingspeed from the bottom to the upper cone of each pair by moving the beltslongitudinally from one point to another on the peripheries of saidcones. Said operation may be performed by means of any suitable andconvenient shipping device. In this instance said result is effected inthe following manner: Between the cones of each pair, at one side andparallel to the axes thereof, is arranged a transverse threaded rod, e,fitted to turn in suitable bearings at each end in frame A, but heldagainst longitudinal movement therein. Each of said rods is providedwith a handwheel, f, whereby the same may be turned, and a forkedbelt-carrier, g, engaging with the belt, is also fitted to travel overeach rod between the bearings thereof, the same being provided with atransverse-threaded opening to receive the threaded rod and with asmooth opening to receive a smooth holding and guide rod, g, secured atthe ends in frame A, at one side of and parallel to the threaded red,the purpose of said rod 9 being to hold the belbcarrier against rotarymotion on the threaded rod, so that when the'latter is turned saidcarrier will be moved along the same in one direction or the other,accordin to which way its hand-wheelf is turn ed. The belt M is therebymoved with it, and in consequence changes the speed of the upper cone,it being increased by moving the belt toward the smaller end of saidupper cone and decreased by reversing said movement. The top cones arefitted to turn in adjustable bearings K, fitted to slide vertically insuitable housings, K Said top cones rest upon the bottom cones, with thebelts M between them, and additional downward pressure may be appliedwhen required by means of vertical holdingscrews it, which may be turneddown against the tops of the adjustable bearings K. Said screws arefitted to turn in cap-plates 1, fastened to the tops of housings K Aconstant pressure is imparted to keep the faces of the disks H againstthe peripheries of the disks D by means of suitable springs, jin thisinstance fitted over the shafts I between the side frame A and the hubsof disks H. desired, any other suitable spring device may be used toeffect the same result.

The frictional power of the disks D against the disks H may be augmentedby providing said disks D with leather bearing-faces 76, as is bestshown in Fig. 1. Upon the outer ends of the shafts K, opposite to thedisks H on shafts I, are mounted the flanged drawing through pulleys N,around which the wire is wound one or more turns in its passage throughthe machine, as is usual in other machines of this class. Between saiddrawing-through pulleys and in a horizontal line therewith are arrangedthe reducing-dies l, which are held in position in the adjustableholders 0, fastened to frame A. structed in the following manner:

A plate, m, having a vertical holdin g-slot in its front side, issecured to frame A, and in said slot is fitted an angle-plate, at,having a horizontal arm, 07/, extending out laterally from the machine,as is best shown in Fig. 8. Said plate a may be adjusted vertically inthe holding-slot of plate m and fastened, after adjustment, by means ofa set-screw, 0, and nut 0, the screw being passed transversely throughthe plates. Upon the horizontal arm n is adjustably fastened the openbox or receptacle p, in the front end of which the dieZ is placedagainst the vertical end thereof, as is shown in Fig. 7. The opposite orrear end of said die-receptacle is made trough-shaped, with the bottomof the trougl'i just below the level of the wire. It is made adjustableon the arm by forming a vertical screw-stud, 01 on its under side, whichpasses through a slot, 41 in the arm n, and is fastened, afteradjustment, by the nut '12, said slot 01 admitting of its beingmovedlaterally toward and from Said die-holders are con the machine tobring the die-opening in the required position. 3y thus constructing thedie-holders 0 it is obvious that the dies I may be readily adjustedeither vertically or laterally, so to bring said dies in any desiredposition, thus admitting of the size of the drawirig-through pulleysbeing varied to suit different requirements. The wire-drawing block P ispreferably arranged vertically, and its shaft 0" is fitted to turn in asuitable bearing, 0', extending out from frame A. The bases of saidblock rests upon the vertical disk 2, secured to one of the shaftsK,coming in. line therewith, and the block is driven thereby; otherwisethe arrangement for driving and regulating said block is the same asthat employed for driving and regulating the drawing-through pulleys N,as will be observed by the drawings. The wire is supplied to the machinefrom a reel, Q, and is drawn forward therefrom through the various dies'to gradually reduce it in size by the block P and drawing-throughpulleys N in like manner to other similar machines. It may be suppliedwith a proper lubricating-fluid in pass ing through said reducingoperation by arranging a main supply-pipe, u,-having suitable branchesand shut-off cocks, r, over the die-holders, adapted to discharge saidlubricant over the wire just prior to its passing through the die. Saidmain pipe u m( y in practice be connected with any suitable reservoir orother means for supplying the same with the lubricating-fl uid. As saidfluid flows out of the die-receptacles p it enters a stationary trough,an, arranged under said receptacles, an d from thence it is in turndischarged through the waste-pipe as, which may in practice be connectedwith a suitable receiving tank or receptacle.

The lubricating-fluid maybe used over and over, if desired, by combininga suitable force-pump with said receiving tank or receptacle for forcingsaid fluid back into the supply reservoir or pipes. My invention, ho\ever, has no relation thereto, and it is consequently not illustrated.

By constructing a wire-drawing machine as hereinbefore described I amen. bled, as will be seen, to adjust the speed of the shafts I K bymeans of the friction-disks D H, and also the wire-drawing pulleys N andblock P, by the friction-cones J L and belt M, so as to vary their speedto a nicety, the shafts being adjusted independently of the wire-drawingpulleys, and each shaft and pulley independent of the other. Being thusenabled to exactly adjust the various parts, and all the parts beingdriven by frictional power rather than gearing, the wire is drawnthrough the machine in a very smooth and even manner, without any jerksor vibratory movements, and in consequence a superior quality of wire isproduced, especially in treating the finer grades, for which thismachine is more especially designed.

I am aware that it is not broadly new to obtain a varying speed oradjustment by means of a pair of friction-disks, as D H. Neither is itnew to effect the same result by means of friction-cones and a beltplaced between them, as J, L, and M, and I therefore limit my inventionto the combination thereof with the other parts of my improved machine,as set forth in the claims.

Having now fully described said machine, what I claim therein as new,and desire to secure by Letters Patent, is
